I have heard that the medieval Catholic Church officially disapproved of cousin marriages up to the level of (IIRC) 17th cousins, but this rule was probably honored more in the breach than the observance.

The medieval Catholic Church defined beavers to be fish, which, in this thread, sounds awesomely sexual but in reality was just about satisfying the urges of a bunch of cloistered monks.

So what? How on earth is that a GQ response to the previous poster's tentative assertion?
